Be careful of automated responses.  What if someone spoofs IP's of legit us=
ers / customers / whatever and your automated response blocks them?  Not go=

I thought about blocking....well, never mind - might pi$$ someone off and a=
ttract unwanted attention...

You might consider mod_security (/usr/ports/www/mod_security) which
can be set up to ban hosts based on behaviour or characteristics.

Or fail2ban (/usr/ports/security/py-fail2ban) is really great, too, in
that it scans whatever logs you want, and can trigger a block in your
firewall if enough violating log entries are found within a particular
period of time. Everything is totally configurable, and there are
plenty of examples that come with it.
